Definitions

  • the field of the invention is drains.
  • disposing the used cartridges in landfills can create incubators for germs, bacteria and various pathogens, and the used cartridges are often a health hazard that require properly disposal.
  • None of the prior art device known to Applicant utilize a combination of a cartridge and a ultraviolet light emitter in a drain to prevent odors from emanating from the drain while sanitizing at least part of the drain where germs, bacteria and various pathogens can develop.
  • the inventive subject matter provides apparatus, systems and methods for regulating a liquid flow through a drain, and which include a cartridge that is sized and dimensioned to be received within the drain.
  • drain means a fluid outlet such as that found in urinals, sinks, tubs, floor drains, or other gravity feed drains through which fluid can flow
  • gravity feed drain means a drain through which a liquid or other fluid flows primarily as a result of gravity.
  • cartridges having a chemical sealant are contemplated, preferred cartridges include a valve subsystem that advantageously replaces the use of chemical or other low-density sealants.
  • the valve subsystem can include one or more valves that eliminate the need for flushing water, while avoiding the problems associated with cartridges having low-density chemical sealants.
  • the cartridge can be used in urinals and other drains that utilize water to flush the drain, or with chemicals to clean the drain housing and cartridge, without degradation of the valves or odor seal.
  • Especially preferred systems each include an ultraviolet light emitter that is configured to emit ultraviolet light, and is disposed within the systems such that ultraviolet light is emitted on at least one of (1] a fluid passageway of the cartridge and (2] at least a portion of the drain downstream of the cartridge.
  • the one or more valves can be gravity flow valves configured to be biased in a closed position, and at least partially opened by a pressure of a liquid against a surface of the valve. Such valves advantageously can operate without electricity, and function to create a closed system, where the valves close automatically once the liquid passes by the valves.
  • At least one of the valves could be an electrically operated valve including, for example, by using a solenoid, a vibrator, or other commercially suitable devices.
  • a solenoid for example, by using a solenoid, a vibrator, or other commercially suitable devices.
  • An exemplary discussion of a cartridge that utilizes a solenoid valve is discussed in U.S. Patent Appl. No. 2008/0295233 filed on May 28, 2008.
  • the one or more valves can be used to regulate any commercially suitable fluid including, for example, water, urine, and combinations thereof.
  • the term “gravity flow valve” means a valve in which the fluid flows through the valve primarily as a result of the force of gravity.
  • the term “gravity flow valve” means a valve in which the fluid flows through the valve primarily as a result of the force of gravity.
  • an electrically controlled valve can include a solenoid
  • an electrically assisted valve can include a gravity flow valve that is assisted in opening by use of a vibrator, a motor to drive an air multiplierTM or traditional fan, or other electrical device.
  • vibrator is defined as any device that causes a vibration within the cartridge including, for example, turbines with offset weights, vibrating motors, and/or any combination(s] thereof.
  • Preferred valves can be skirt valves, which possess numerous advantages over known one way valves such as umbrella valves and duckbill valves.
  • the skirt valve can be mounted about a stem or post to create a 360 degree opening that is less likely to be jammed by solid items.
  • the skirt valve typically lacks a spoke to hold the center of the valve in place, and therefore lacks the problems associated with the spokes catching foreign objects.
  • the skirt valve can have a thicker first portion that is coupled to a stem or post of the cartridge, and a thinner second portion that allows for greater flexibility of the valve.
  • the skirl valve can be (1] much more rigid than an umbrella valve to (a] keep the valve closed when not in use and (b] prevent back pressure in the drain pipe from opening the valve, while (2] the ends of the skirt valve are flexible to allow for fluid flow.
  • the valves can have a flexible, synthetic membrane that opens when a pressure on an upper surface of the valve exceeds a predetermined threshold. This is beneficial because the valves open when fluid is present on the surface of the valve, but otherwise remain closed.
  • the valves advantageously allow urine or other fluid to pass through to a drain pipe while preventing potential sewer gas from permeating into a facility room or other environment.
  • valves can help prevent backflow in the drain pipe from causing damage, since the increased pressure downstream of the valves would force the valves closed and thereby prevent the backflow from exiting through the cartridge.
  • any commercially suitable valve(s] could be used including, for example, duck bill valves and umbrella valves.
  • at least one valve could be a non-gravity flow valve including, for example, mechanical check valves and other one-way valves, ball valves, gate valves, and any other commercially suitable valve(s] and combination(s] thereof.

  • the housing and the insert could collectively be inner and outer chambers, upper and lower chambers, or left and right chambers, respectively, or other commercially suitable configuration ⁇ ].
  • the one or more valves can be disposed within a user-removable insert of the cartridge. In this manner, a user can easily access the drain pipe coupled to the cartridge by simply removing the insert, such as to eliminate any blockages found therein. This allows for a plumber's snake or other tool to be ran through the cartridge without requiring removal of the cartridge itself.
  • disposed the valves within the insert provides easy access for cleaning and maintenance of the valves.
  • the cartridge can be fluidly coupled to a P-trap or other fluid trap to provide an additional drain seal.
  • the fluid trap can be at least partially disposed within the cartridge.

  • Cartridge 102 can include at least one valve 136, and preferably includes first and second valves 136 and 138. Contrary to prior art systems having a single valve including, for example, U.S. Patent No. 6401266 to Mitchell et of.; U.S. Pat. Appl. No. 2006/0010565 to Cummings (publ. May 2006]; U.S. Pat. Appl. No. 2006/0207005 to Janssen (publ. Sept. 2006]; and W1PO Patent Appl. No. 2009/040524 to McAlpine (publ. April 2009], the present cartridge utilizes at least two valves and thereby provides additional protection against the escape of odors from a drain pipe. For example, even if the primary first valve 136 was somehow stuck open by a toothpick or other debris, the secondary valve 138 would still prevent odors from escaping the drainpipe.
  • valves comprise gravity flow valves that are biased closed such that the valves 136 and 138 are closed when not in use.
  • Each of valves 136 and 138 can comprise a skirt valve, although other commercially suitable gravity flow valves could alternatively be used including, for example, umbrella valves, duck bill valves, and other flexible valves.
  • An exemplary embodiment of a skirt valve is shown in Figures 16A-16C. Skirt valves are defined to include a rim extending from a core of the skirt valve where the rim comprises a rigid portion with a flexible tip.
  • At least one of the valves 136 and 138 could alternatively be a non-gravity flow valve including, for example, needle valves, ball valves, gate valves, poppet valves, plug valves, globe valves, butterfly valves, and diaphragm valves.
  • the valves 136 and 138 can have a flexible, synthetic membrane that can comprise any commercially suitable materials] including, for example, silicon fabric or other synthetic and/or flexible materials, or combinations thereof, which provide protection to the valves from significant damage or degradation by urine fluids and cleaning solvents.
  • the valves thereby advantageously allow urine to pass through to the drain line without allowing odors to permeate up from the drain line.
  • the second valve 138 can be disposed downstream of the first valve 136.
  • the first and second valves 136 and 138 are separated by a distance less than or equal to six inches, and more preferably, less than or equal to three inches, as shown in Figure 1 A. All commercially suitable configurations are contemplated for the first and second valves 36 and 138, and preferably, the valves 136 and 138 are biased to be convex in the upstream direction.
  • the first valve 136 is more rigid than the second valve 138.
  • valves 136 and 138 are preferably disposed within insert 126, which advantageously allows the valves 136 and 138 to be removed for cleaning or replacement without necessitating removal of the cartridge 102.
  • an interior of the insert 126 can define a passageway configured to allow fluid to flow from the first valve 136 to the second valve 138.
  • at least one of valves 136 and 138 could be disposed elsewhere within cartridge 102.
  • the valves 136 and 138 can be disposed such that an end portion of each of valves 136 and 138 is seated beneath first and second sloped portions 194 and 1 6 of an interior of insert 126. In this manner, any backflow or pressure beneath the valves 136 and 138 will keep the valves 136 and 138 pressed against the wall of the insert 126, and thus the valves 136 and 138 can remain sealed.
  • valves 136 and 138 have a varying thickness along its respective radius, such that each of valves 136 and 138 is sufficiently thin at respective outer 5 mm edge intervals 137A and 139A to allow even small amounts of urine or wastewater to pass through valves 136 and 138, while retaining sufficient strength for durability at the inner portions 137B and 139B, respectively.
  • the outer 5 mm edge interval 137A of the first (upper] valve 136 has a first average thickness that is less than 95% of a second average thickness of the outer 5 mm edge interval 139A of the second (lower] valve 138.
  • the first average thickness of the outer edge interval could be less than 90%, 85%, 80%, 75%, or 70% of the second average thickness of the second outer 5 mm edge interval 139A.
  • the edge interval of the valve could be the outer 1 mm, 3 mm, 7mm, 10 mm, 15mm, 20 mm, and so forth, of the valve and will likely depend upon the size and dimension of the valve, and the fluid that the valve regulates.
  • the width of the outer edge intervals 137 A and 139A will likely be proportional to the overall width of the valve.
  • the term "outer 5 mm edge interval” means the portion extending from the outer edge of the valve inwards by a distance of 5 mm.
  • the outer 5 mm edge interval of a circular valve having a radius (r] of 20 mm is the outer 15 - 20 mm from a center of the circular valve, or an area represented by the formula: ( ⁇ * r 2 ] - ( ⁇ * (r - 5] 2 ]. In this example, the area would be approximately 549.8 mm.
  • the term "outer 1 mm edge interval” means the outer 1 mm edge portion extending about an exterior of the valve.
  • square, ovular, and other commercially suitable sizes and dimensions of valves could alternatively be used, and the outer x edge interval would still be applicable.
  • the thinner first valve 136 advantageously ensures that urine will easily flow past the first valve 136 and eliminate residual odors, while the thicker second valve 138 ensures that the second valve will remain sealed even if there is backfiow or back pressure downstream of the second valve 136.
  • Each of the valves 136 and 138 can be anchored at a center portion of the valves 136 and 138 to a stem 130. In this manner, ribs are not needed to anchor the valves 136 and 138, and therefore solids such as cigarettes, chewing gum, and coins are less likely to clog the cartridge 102.
  • Cartridge 102 can further include a fluid trap 118 that is fluidly coupled to cartridge 102.
  • the fluid trap 118 is at least partially disposed within the cartridge 102, and more preferably, in the lower section 106 as shown in Figures 1A-1B.

  • the insert 126 can comprise a single piece that includes extended portion 128.
  • the fluid trap 118 can also be permanently formed within the cartridge 102 by use of a baffle or wall-like structure, as shown in Figure 4.
  • the extended portion 128 is advantageous because the additional length assists in preventing cross-threading of the insert 126 when it is inserted into cartridge 102.
  • Fluid trap 118 acts as a further barrier against odors emanating from the drain pipe in addition to first and second valves 136 and 138.
  • cartridge 102 can have triple means of protection against odors.
  • the fluid trap 118 can help prevent the possibility of backfiow from the drain pipe exiting through cartridge 102 because any backfiow would increase the pressure downstream of the valves 136 and 138 and thereby keeping them closed. This is particularly beneficial for urinals and floor drains, because these drains are disposed near or at ground level and are often the first drains to experience problems with backflow.
  • Fluid outlet 124 can be fluidly coupled to the fluid trap 118 in the lower section 106, such that excess fluid can exit the fluid trap 1 18 through a drain pipe 172.
